' which Figure 1 is an enlarged perspective view of a device embodyingmy invention; Figs. 2 and 3 are enlarged perspective views of the twomembers composing the device separated from each other; and Fig. 4 is atransverse vertical section on the line IVIV of 1; I

The object of my invention is to provide a simple and eflicient devicefor threading needles, capable of being operated with one hand, andadapted for use with various sizes of needles, and for both hand andsewing machine needles.

With this object in'view, my invention consists in the novelconstruction, arrangement, and combination of parts, all substantiallyas hereinafter pointed out in the appended claims.

different sizes of needles.

The device consists of a front member 2 and a back-member 3 suitablyunited to each other. In the construction shown in the drawings, theback-member 3 is shown as having recessed lips 4 at its ends whichreceive and retain the ends of the frontmem her. The front-member isformed at intervals with a number of vertically-extending grooves 5 madeof different sizes to receive Each of these grooves has an angular lowerportion so shaped that the needle cannot be introduced except in itscorrect osition, and an upper portion 5 of conical orm which serves as aguide to facilitate insertion of the needle. These needle-receivinggrooves are formed in the inner or rear face of said member, and aconical thread-receiving aperture 6 is formed through the member at eachgroove and communicates therewith opposite the point which is occupiedby the needle, shown in dotted lines in Fig. 4. Leading to the upperedge of the member from each of these aper tures 6 is a vertical slot 7.

The back-member 3 is formed with a thread opening 8 opposite each of theapertures 6 and with vertical slots 9 communicating with each of saidapertures for the purpose of permitting the ready withdrawal of thethread after the needle has been thread ed. The two members arepreferably made of sufficient thickness, so that their lower edges forma base upon which the device is self-supporting. The members areshouldered or cutaway at the bottom at one end as shown at 11, in orderto enable the device to be used upon a sewing machine, its cut awayportion enabling the threading place at that end to be extended over thepresser foot of the machine. The groove 5 at this point is extendedbelow the aperture 6 in order to receive the greater length of theneedle below the eye.

The operation of the device will be readily seen. The needle to bethreaded is inserted in one of the grooves 5, which will cause its eyeto be brought into alinement with the apertures 6 and 8. The thread isthen entered through the aperture 6. The needle is then withdrawn, theslots 7 and 9 facilitating the withdrawal of the thread.

The advantages of my deviceconsist in its simplicity, in itsadaptability to different sizes and kinds of needles, and its capabilityfor use with one hand.

Changes may be made in the details of construction and arrangementwithout de parting from my invention, since hat I claim is 1. A needlethreader comprising a body provided in its top with a needle-receivingsocket having a closed bottom within the body, a threadreceiving passageintersecting the front and back of the body and the socket above thebottom of the latter for alinement with the eye of a standard needle,

anda thread escape slot longitudinally intersecting the socket, the top,front and back of the body and thread passage, substantially asdescribed.

2. A needle threader comprising a body made up of front and back rigidlyconnected members having a needle-receiving socket formed between themand intersecting the top of the body, the bottom of the socket beingclosed within the body, a thread passage intersecting the front and backmembers and the socket above the bottom of the latter for alinement withthe eye of a standard needle, and a thread escape slot longitudinallyintersecting the socket, the front, back and top of the body and thethread passage, substantially as described.

3. A needle threader comprising a body having a supporting portion torest upon the ICC IIO

top of a sewing machine and provided with a portion capable ofoverhanging the presser foot of a sewing machine, the latter portionbeing provided with a needle receiving socket having a closed bottomwithin the body, athread passage intersecting the front and back of thebody and the socket, and a thread-escape slot longitudinallyintersecting the socket, the top, front and back of the body and thethread passage, substantially as described.

4. A needle threader comprising a body capable of resting at its baseupon a sewing machine and provided in its top with a needlereceivingsocket having a closed bottom Within the body, that portion of the bodybeneath the socket being cut away to permit of the socketed portionoverhanging the presser foot of a sewing machine, a thread passageintersecting the front and back of the body and the socket above itsbottom, and a thread-escape slot longitudinally intersecting the socket,the top, front and rear of the body and the thread passage,substantially as described.

5. A needle threader comprising a body capable of resting at its baseupon a sewing machine and provided in its top with a pair ofneedle-receiving sockets closed at their bottoms, each socket beingpierced by a thread passage intersecting the front and back of the body,and a thread-escape slot longitudinally intersecting the socket, the

top, front and rear of the body and the neath one of the sockets topermit of" the latter overhanging a presser foot, the thread passage ofthe latter socket being disposed above the bottom ol the socket .lorahnenient with the eye of a sewing machine needle, and

the thread passage of the other socket being disposed above the bottomol said socket l'or alinement with the eye of a hand-needle,substantially as described.

6. A needle-threading device having one end portion cut away at itsunder side to lit over the presser foot of a sewing machine, aneedle-receiving passage therein above the cut-away portion, athread-receiving passage intersecting the lower end portion of theneedle-receiving seat, andv a thread releasing slot extending outwardlyfrom each thread-receiving passage; substantially as described.

7. A needle-threading device consisting of a backmember formed with lipsat its ends, a front member having its end portions engaging and held bysaid lips, and a plurality of needle seats and thread passages formed insaid members; substantially as described.
